CMakefiles and makefile do not specify -std which results in compilation failure
Opened this issue · 1 comments
I am using Linux Mint 18.1 with GCC 5.4.0-6 and CMake 3.10.0-rc1. I perform the following:
mkdir build
cd build
cmake ..
make -j
I get the following error message:
make[2]: Entering directory '/home/nlbutts/projects/sjpeg/build'

If I update the CMakelists.txt file and add -std=c++11, everything works fine.
